You can install an old version of the software, but the database schema 
updates are one-way-only.  You can upgrade, but you cannot downgrade.  
When you run mythtv-setup or the master backend and let it upgrade the 
database, it will automatically produce a dump file.  Should you wish 
you revert, a few simple commands will let you drop your database, and 
recover from that dump file, however you will lose any information 
modified since the moment you dumped.  If you made any recordings after 
that point, they will end up orphaned.
